10 panel dodecagon. tie the end of the panels at the t post, dont bend around. if you put a t post in the middle of each panel that is fine, just don't bend the panels into a circle or else when you put a row of barbed wire above it will be inside the panels and make for a precarious situation. took us an hour to build each one this summer including stringing the barbed wire
I only used 6 panels and have had as many as four dear in the pen. I do agree that the more panels the better but in some areas it just isn't really an option to build it that big. I also made it a circle and didn't use barbed wire. What was the purpose of adding barbed wire?
Oh, and it's working great so far.
